Application filed Iebruary 4,1925. Serial 80,76,709.

This invention relates to typewriting machines, and is shownin connection with a machine of the type illustrated in a atent to G. G. Going, No. 1,305,091, dated ay 27,

5 1919; although the invention is not limited to this type .of machines. In said machine the types are mounted upon the ends of slides, each slide carrying three types; and

type-bars are moved against the platen by to means of keys.

It is an object of the present invention, in this and other types of machines, to increase'the number of rows of keys, or in other words to eliminate one of the usual case-shift keys; and this object is accomplished in a manner that permits a reduction in the number of type-bars, thereby giving substantial advantages, and not only saving in cost and room, but also enabling the typebars to be directed less obliquely aga nst the platen, thereby improving the type-impressions on the work-sheets.

' According to this invention each type-bar is operable by two keys, so that an increase of the number of keys to say fort -two may be accompanied by a reduction 0 the number of type-bars to say twenty-one, thus gaining substantial advantages.

Each type-bar carries four types, and 1s operable by depressing either oftw'o typekeys, each key bringing into use two of the types; a shift-key is.-provided for shifting the platen from lower to upper case posi-.-

tion. When the platen is in normal position; depression of on'eof said two keys will drive the type-bar to the platen, printing a lowercase type, while, if the platen is in an uppercase position, the same type-key will print an upper-case type on said type-bar.

When the other of said two keys is depressed, however. it not only drives the typebar to the platen, but also automatically shifts the individual type-bar to bring into use the other lower and upper case types thereon.- One-half of the type-keys there: fore are capable of shifting their own typebars individually atthe printing strokes. One way of accomplishing this individual type-bar -shift is toprovide an individual shifter for the ty e-end of the type-bar, and connect said shi terto be operated by the type-key.

said patent are usually arranged radially in a horizontal position in front of the platen, and have a sliding rec'iprocatory movement to and away from a common printing point.

Due to the magnitude of the angles at which the end type-bars strike the platen, the capacity of such machines has been limited to about thirty type-bars and thirty type-keys, and, in order to provide a fullcom lement of characters, each type-bar with a ew possible exceptions, has three ty es thereon, necessitating the use of two shi t-keys, there being one key for each outer course of types. The keys, as shown in said patent, are arranged in three banks or rows which is obectionable in some well-known respects.

A feature of this invention, relates to means'toenable the use of a four-bank standard keyboard. in a machine of this I kind, although applicable also to other ma chines. In carrying'out the invention thrnumber of type-bars employed (preferably 21) 1s equal'to half the number of characterkeys (42) in the keyboard.

Each type-bar is shown in the drawings provided with a'lo'wer group oftwo' lowercase types, and anupper group of two upper-case types. The type-key-levers associated with the two lower banks of keys are shownin one arrangement of the invent on ,connected to operate the type-bars in the usual way in this type of'machine, to thus cause the lower type of the lower-case group to'print. The key leve'rs associated with the two upper banks of keysv also operate the type-bars associated with the two lower banksof keys, and at the same time shift the type-bars individually and automatically to cause the upper type-of the lower-case group to print.

In another arrangement of the invention the two middle banks of keys, which are a most used, are connected to operate the typebars only. The upper bank and the-lower bank of keys, which are not used so he quently, are connected to also shift the typebars while they are being actuated towards the printing oint. i

To bring a out the shifting of the typebars each key-lever of the two upper banks of keys in the one arrangement, or each keylever of the two outer banks of keys in the other arrangement, has connected thereto a The type-bars in the machine shown in plunger which embraces the associated tgpebar, so that said type-bar may be lifte by said plunger as the key-lever is actuated, thus selecting the desired type, of the typebar.

A ty e-guide is provided with which the forward ends of the type-bars co-operate to register the imprint of the type at the printing point. This type-guide is shiftable with each case-shifted type-bar. For this purpose each. type-bar shifting plunger is provlded with a lug or projection, WhlC-h lugs engage with a universal bar connected with -t'he type-bar guide to shift the latter to the 'desired position, so as to be effective to gu de the type-bar, at the printing point, in its case-shifted position. V

Provision is made to complete the shift-v ing of the type-bar immediately before the type-bar reaches the platen. To this end there is provided a yielding connection between each type-bar shifting plunger; and 1ts associated key-lever which enables a further depression of the key-lever to complete the printing stroke after the type-bar has been arrested in its shifted position by suit- 1 able stop-devices. By suitably locating the point of attachment of said connection upon said lever, the extent of the printing stroke of the lever exceeds the extent necessary to shift the type-bar, thereby assuring that such shifting is completed before the typebar prints. 7

It will be understood that with this arrangement the number of type-bars is decreased with a consequent decrease of the total angle occupied by the type-bars, which makes the angles at which the outer typebar's approach the platen more favorable, in other words, more nearly perpendicular to the platen.

In order to print with the upper-case types, the platen is shiftable to the groups v end a lever 38 pivoted on the bracket 30 and of upper-case types on'the type-bars.

The invention is herein illustrated as having a ease-shift mechanism of the type shown in the patent to G. G. Going, No.

. 1,308,411, dated July 1, 1919, with some modifications that are shown in the patent to- N. H. Anderson, No. 1,155,635, dated October 5, 1915.

Features of the present invention may be used with other kinds of type-bar machines.

Other features andadvantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a cross-sectional view in ele vation through the center of the machine, showing the type-bar mechanism in its normai position.

Figure 2 is a plan view partly in crosssection, showing the type-bar mechanism and the keys operatively connected in pairs.

Figure 4 is a cross-sectional view in elevation through the centerflof the machine,

showing the type-bar mechanism in its operated position.

Figure 5 is a plan view showing a modified disposition of the keys operatively con nected in pairs.

This invention is shown for example in connection with a Noiseless typewriter. The invention is also useful with other varieties of machines. The type-action may, for example, be like that shown in the previously-mentioned patent to G. G. Going, No. 1,305,091, in which there is shown a machine-frame 10 having a keyboard at. the front and a movable platen 11 mounted in advance of the platen lland have reciproeating movements guided between plates 25 and 26. The connection between a key lever Band at type-bar 24 to cause printing when the former is operated, includes a pull wire 27 fastened to the key-lever and con,- ne'cted to a rocking lever '28 fulcrumed to the a platen-carriage 12 at the rear, the latter depending arm 29 of a bracket 30. The

lever 28 engages a .short arm 32 of a bellcrank lever 33 pivoted on bracket 30. The long arm 34 of .said bell-crank lever 83 is connected to a link 35 having at its forward end a weight 36, and at its rearward connected to alink 39 pivoted to the typebar 24. The universal-bar 40 is actuated by a straddling piece 41 on the bell-cranklever 33. The bell-crank-lever 33 is held in normal position by a spring 42. To hasten the rebound of the type-bar after printing, the arm 43 of the-bell-crank-lever"engages a ad44.

type-key for each, type-bar, the keys being agiianged in three banks, which is objectiona e.

- In my present invention I have provided a 3 standard four-bank keyboard having the usualcomplement of keys, Said keys-are paired and connected to the 'type bars insuch; manner that each type-bar is operable by two keys, either of which may print two characters, as will be shown. -The'number of type-bars is substantially V one-half the number of the keys. Each type-bar is preferably provided with a .lower group of two lower-case types and 46' and an upper group of two upper case types 47 andl48 The type-key-levers 13 associated with the two lower banks ofkeys 15 areconne'cted to operate the type-bars 24, in-the manner alreadytdescribed, to cause the types 450i the lower-case group to print.

The key-levers 13*,assoc1atedwith the two 7 upper banks of keys 15 are each provided with a pin 49. Each pin 49 overlaps a keylever 13 of one'of the two lower banks of keys which, has its types 45 and 47 on .the same typerbar; is depressed, the pin 49 on its key-lever 13 will engage with the key-lever 13 of a typekey 15, depressing the key 15 and its keylever 13 downwardly, which in turn .will

.drive the type-bar 24 towards the. platen.

During the downward motion of the key 15, means which have been key-lever 13 and its type-bar 24 are efiective to individually and automatically shift said type-bar and thereby cause its type 46 to print. Y

To bring about the shiftingof. the typebars 24, each of the key-levers 13 has pivot-,

ally connected to it a link 50 slida'bly mounted in a loop 51 at the lower end of a link 52, which in turn slides in a loop 53 at the upper end of the link 50, and is pivotally'conne cted at 54 to one end of an arm 55 swingable about a pivot 56 on a bracket- 57 fixedon a bar 58 of the plate 26. At its other end, the arm-55 is provided with a slot 59 which-engages-a pin 60 of a plunger 61 which embraces the type-bar 24 and guides its sliding movement. When its key 15 in: one of the two upper banks' is depressed,

it will pull its link 50 down, and through the reaction of a coupling spring 62 on the link 50, the link 52 will be pulled down, swinging the arm 55 about its pivot 56 and forcing the plunger 61 up, which in turn will lift the type-bar 24 so as to bring the type 46 in position toprint. The plungers -61 are guided up and down in slots 63 formed 'in the arcuate edge of the plate 25 and said "slots have, their outer ends closed by a bar 64 fastened-at its'ends to the plate 25 by 7 means of screws 65.

, In order to limit the upward and downward movement of the plungers 61, provision ,is' made of lugs 66 and 67 on each plunger 61 to engage a forwardly-extending plate 68 fastened on the plate 26 by screws 69. When a plunger is being moved upwardly by the depression of itskey 15, its lug 66 will en- When one of'the keys'15 provided between its- The yieldingconnection, due to the Spmfig '62, between the links 50- a'ndf52. enables a further, depression of, the key '15, so that the type-bar 24 willthus have reached its. a

The link -52 is provided with a 'sto 7O fastened to it, o engage the loop 53 an hold the links 50 and '52 against the reaction of the spring 62 in their normal re- -lation.

The typebars 24 are guided at oneend by projections 71'and 72 on the plates 25 and 26," respectively, and laterally guided by the slotted plate 73 suitably fastened to the plate 26. To guide the type-bars and register'the types at the printing point, pro

vision is made of a type-registering guide formed by plates 74 and 7 5'. Means are provided to shift said guide co-relatively with the shifting of the type-bars 24. To this end,

thegplungers 61 are each providedwith a lug -76 underlying a universal-bar 77 fast on arms 78 fixed at one end to a rotatable rod 79 mounted in downwardly-extending arms 80 of the plate 26. .The'arms 78 have pivotally connected to themat their outer ends upwardly-extending rods 81, vertically movable in a slot 82 of an arm 83 attached to the plate 25. The top and bottom guideplates 74 and 75 properly spaced apart are fastened to the-rods 81. When a plunger 61 is operated to lift. its type-bar 24, the llig 76 will engage the universal-bar 77, swinging the arm about its pivot and lifting the rods 81 with the guide-plates 74 and 75 vertically upward. To return-the guide-plates to their normal positions, provision is made of springs 84 mounted on the rods 81 between .the movable guide-plate 7 5 and the fixedarm 83, so that when the guide-plate 75 is, raised, throughthe action of the lunger 61 engaging the universal-bar 77, t e springs 84 will be compressed, and when the'plunger returns to its normal position, the springs will expand and thereby return the guide-plates .74 and 75 and the universal-bar 77 to their screws 97. The lever 93 has a rearwardly- W extending arm 98 pivotally connected by a link 99 to an arm 100 integral-with a rockshaft 101 trunnioned in the machine frame.

A second arm 102 integral with the rock-' I shaft 101 is attached to a link 103'supporting a rail 104 on which the carriage 12 is mounted for movement. When the shiftkey 85 is depressed, the link 103 will be moved vertically upwardly, thereby lifting the carriage 12 and bringing the platen in position to allow the upper group of types to print. In order to insure vertical movement of the .carriage, it is guided by means of a link 105, shown in the patent to Anderson No. 1,155,635, and an upwardly-extendingportion 106 of a tie-rod 107.

To adjust the platen when webs of different thicknesses are used, there is a graduated plate 108 co-operating with an indicating finger-109'fast to a rearwardly-extend- .ing shaft 110 threaded at 111 into the tiefrod 107. By movement of the finger 109, the. platen will be moved to or away from the'types.

- The arrangement of the keys 15 and 15 is not limited to the manner shown in my application, but may be arranged in various ways. In another arrangement (Figure 5) the two middle banks of keys, which are most used, are connected to operate the type-bars only. The upper bank and the lower bank of keys, which are not used so frequently,are connected to also shift the type-bars while they are being actuated towards the printing point.

It will be seen from the foregoing description, that I have provided means whereby the number of type-bars in a type-writ- I ing machine may be reduced to substantially one-half the number of keys required to operate the type-bars, and thus I eliminate the necessity of reducing the keyboard of the machine in cases when, due to compactness of the machine or due to the peculiar design of-the type-bar mechanism, it may not be feasible or practical to have as many typebars as it'would be necessary to provide to suit the requirements of a standard keyboard.

The type-bar shifting mechanism which forms the subject of this invention, is illustrated in connection with a type-writing machine in which the type-bars are disposed for rectilinear travel, because this is one case in which the advantage of having the number of type-bars reduced, and the number of keys increased, is obvious, as it permits the building of a machine of this type having a full keyboard, while at the same time it reduces the striking angle of the outer type-bars. However, I do not wish to .bar, said means including connections to limit my inventionto this type 'of machine, as the same featuresmay be used 'to advantage in any type of machine, especially when for any reason it is desirable to reduce the number of'type-bars, or to increase the a plurality of types and each carrier having a case-shiftable guide for determining the direction of its movement toward the platen,
